/*
 * Notes about item creation:
 * 1) It is similar in syntax to the dm create command.
 * 2) It requires a player to have a buildfacility below him, a tool in his
 *    possesion, and materials to build with.
 * 3) The random roll is done in a loop, so if the player tries to make 100,
 *    he makes 100 checks.
 * 4) Exp is given only on succ. creations, but materials are used regardless.
 * 5) The properties of the tool are stored in tooltype and weapontype.
 * 6) The properties of the buildfacilities are stored in tooltype.
 * 7) For now, all ingredients must be type 73 INORGANIC.
 * 8) The player can attempt to create any arch, but item_power and value
 *    will prevent most artifacts from being built.
 * 9) The code allows magic bonuses up to +5.  It is not trivial to make a +5
 *    item.
 *10) If you ever extend it beyond +5, add more gemtypes.  Currently the code
 *    looks for gemcost gems per item, per plus.  So a +5 item requires
 *    gemcost pearls,rubies,emeralds,sapphires and diamonds.  Not cheap.
 *11) There are a zillion if statements in this code.  Alot of checking takes
 *    place here.  All of them are needed.
